In a two-factor ANOVA assessing the effects of factor A and fac the following are included in the between treatments variance of this meas a. the variance due to the interaction of Ax B b. the variance due to factor B c. the variance due to factor A d. all of the above variances are included which situation 2.) The term "factorial ANOVA" should NOT be usedto describe the design of a study i a. when a researcher manipulates the levels of one factor b. when a researcher measures the values of two or more variables c. when a researcher manipulates the levels of two or more factors d. both answers a and b 3.) Why would you use a two-factor ANOVA over a one-factor ANOVA? a. in order evaluate the main effects of two variables simultaneously b. in order to evaluate any interaction effects that may occur between the two variables c. in order to acquire a better understanding of how mutiple variables influence behavior d. all of the above which f the flowing bNOT r din any of the F-ratios evaluatng the main and rter independent-measures, two-factor ANOVA? raction effects in an a.

Explanation / Answer

Please post 1 question per post.

1. "between variance" the variance among treatments,

The total variance can be divided into "In - between variance" and "within variance". out of which in between variance is the one which is being explained by whatever factors and interactions of those factors.

Hence, the right answer to this question is option D)

by definition between variance is defeined as "how much of the variation in the response variable(s) is explained by your explanatory variable(s)"
